bgwriter update question

I'm running on 7.4.5 (pre bgwriter) and moving to 8.2 in 3 weeks. I turn
fsync off on my testing server. When I update a table I expect the file in
the base directory to remain the same size until the next syncpoint when it
would then update. But it increases immediately. I thought updates remain in
memory until syncpoint in pre-8.0. Am I missing somethng?

Thanks for your time
